Description

A connection component and connection system

Technical field

The utility model relates to a connecting assembly including a first connecting piece and a second connecting piece. The utility model also relates to a connecting system; wherein the connecting assembly is used to connect the first member and the second member, especially for connecting glass. plate.

Background technique

In the prior art, panels are installed on walls, doors, furniture and other components through screws or bolts, three-in-one connectors or shelf components, such as "Close to the Wall" disclosed in Chinese Patent Publication No. CN206261202 type cabinet", by setting jacks on the side panels, the upper fixed plate and the lower fixed plate respectively, and then inserting the two connecting posts of the connector into the jacks of the side panels and the lower fixed plate or the lower fixed plate respectively. holes to mount the upper or lower fixing plate on the side panel. However, during use, foreign objects or external forces can easily drive the upper fixed plate or the lower fixed plate upward or lift up in the vertical direction, causing the upper fixed plate or the lower fixed plate to separate from the side plate, which makes the use less safe.

For this reason, the "Adjustable Shelf Positioning Fastener Structure" disclosed in Taiwan Patent Announcement No. TW578500U uses the upper and lower clamping pieces of the positioning fastener to clamp the upper and lower sides of the shelf respectively. The movement of the laminate in the vertical direction is restricted, thereby preventing the laminate from being pushed up or lifted due to force. However, since the upper and lower clamping pieces of the positioning fastener restrict the laminate from being installed from the side, there is a gap between the laminate and the frame body, and the aesthetics is poor; in addition, the upper clamp of the positioning fastener The thickness of the holding piece is relatively large, so the object is easily stuck by the upper clamping piece when moving on the upper side of the laminate, which easily causes damage to the object and makes it inconvenient to use.
